Origin
Meaning and origin of Dinardo
The surname DiNardo is of Italian origin, originating from the southern regions of Italy, particularly in the area around Naples. It is believed to have emerged in the late medieval period, around the 13th or 14th century.
The name DiNardo is derived from the personal name Nardo, which itself is a shortened form of the Italian name Bernardo. Bernardo is derived from the German name Bernhard, which means "brave bear." The prefix "Di" in DiNardo is a common Italian surname prefix indicating "of" or "from."
One of the earliest recorded instances of the name DiNardo can be found in a document from the 16th century, which mentions a certain Girolamo DiNardo, a merchant from the city of Naples. Another early reference is in a church record from the late 17th century, which lists the marriage of Antonio DiNardo and Maria Rossi in a small town near Salerno.
In the 18th century, a prominent figure with the surname DiNardo was Francesco DiNardo, a lawyer and judge who served in the courts of the Kingdom of Naples during the reign of Charles III of Spain. He was born in 1712 and died in 1789.
Another notable individual was Giuseppe DiNardo, a painter and sculptor from the town of Avellino, who lived in the early 19th century. His works can still be seen in some of the churches and palaces in the region around Naples.
Moving into the 20th century, one of the most renowned individuals with the surname DiNardo was Vincenzo DiNardo, a composer and conductor who was born in Naples in 1896 and died in 1967. He composed several operas and symphonic works, and conducted orchestras throughout Europe and the Americas.
It's worth noting that the name DiNardo has also been associated with several place names in southern Italy, such as the town of Nardò in the province of Lecce, and the village of Nardo di Pace in the province of Benevento.
Overall, the surname DiNardo has a rich history that can be traced back to the medieval period in southern Italy, with roots in the personal name Nardo and connections to various places and notable individuals throughout the centuries.

The bar chart below shows how Dinardo bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Dinardo surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Dinardo (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
